Create Bash Helper-Functions Script

[tajmone]

In assets/sh/:

• [ ] Create new _helper-funcs.sh script for generic Bash helpers:
  • [ ] Move therein the non-build related generic Bash funcs from _build-funcs.sh, which is growing too big.
  • [ ] Add functions to convert absolute paths (inside env-vars) from Bash notation to Win format, and vice-versa:
    • [ ] AsbPathBash2Win — e.g. /d/some/path → D:\some\path
    • [ ] AsbPathWin2Bash — e.g. D:\some\path → /d/some/path These are useful when interacting (in Bash for Win) with some third party tools that require parameters in a specific path notation, or for the returned paths values of some tools, which might be in Win notation and need to be converted. For example, see alan-if/alan-docs#66 on problems using asciidoctor-fopub under Bash for Windows.
  • [ ] Add a function to check for availability of third party tools, and that the correct version is available. It should accept parameters to determine the app name, how to query for its version number, how to extract it from the output and compare it to some expected version number passed by a parameter. It should also handle errors elegantly and print good error messages.

We'll Use Rake Instead!

None of the above really matters any longer since we'll be switching to Rake to handle all the aspects of the toolchain; so we'll be using Ruby code to handle all our needs (and with Rake many of the above are not even needed anymore).
